Classifier Visualization

I’m currently working on a new keywords API for uClassify. This will allow users to get information about what words that are good discriminators for certain classes. To test this API I spent last weekend to built a visualization application for urlai.com.

Here is a screenshot how the visualization prototype show data:

I would very much like to get some feedback on this, you can try it here, please comment below.

1) Good – I will see if I can improve the zooming, it seems to be a problem with some browsers who likes to start scrolling instead.
2) In this first draft of the keyword api I am not sending probabilities or frequencies, but will consider adding it.
3) Good point, I will try to add something like that for the next version. Right now the alpha (brightness) of the classes are scaled depending on their probability. All keywords inherit this alpha. I also think coloring the clusters would help.
